BCS superconductors depend on electrons combining into Cooper pairs. I find this phenomenon to be confusing because the electrons in the Cooper pair have equal and opposite momentum. Why don't the electrons in the pair each go their separate way? I found a helpful paper that describes the spatial structure of these Cooper pairs, which are kind of like a giant helium atom where the electron pair cloud surrounds ion lattice oscillations.
